I think he was also in "The Wrath of Dark Kat" as the Megakat Nuclear Plant technician who says "They've breached the reactor. Everybody get out. Get out!"

That's Hal Rayle (Steel). Paulsen isn't credited for The Wrath of Dark Kat. His first appearance in the show is in Night of the Dark Kat, as Hard Drive, Al (replacing Frank Welker), the rookie commando at the beginning and the little boy's father.

Peter Mark Richman is a veteran character actor who's played a ton of roles in his decades-long career. He's one of those guys where you might not recognize his name, but once you start watching old TV shows and movies, you see him everywhere. For more info, check out his entries at Wikipedia and IMDb. Speaking of which, IMDb credits him as "KatCo Crewman #1", although I wonder why they would ask a relatively-well known actor like Richman to play such a bit part.
